Upende ovimbela ukugqwala

Upende ovimbela ukugqwala uhlobo oluthile lwezinto ezidlala indima yokulwa nokugqwala, uvimbela ukugqwala kwensimbi futhi uthuthukise umphumela wokuvikela wefilimu yopende ebusweni bensimbi. Indima yopende ovimbela ukugqwala ingahlukaniswa ngezigaba ezimbili: upende ovimbela ukugqwala ngokomzimba kanye nopende ovimbela ukugqwala ngamakhemikhali, lapho upende ovimbela ukugqwala ngamakhemikhali ungahlukaniswa khona ngokuthinta ukugqwala kanye nohlobo lwesibili lwesenzo se-electrochemical. Izinto ezidlala indima yokuvimbela ukugqwala zifaka phakathi i-red pink powder, i-iron red powder, i-composite iron titanium powder, i-aluminium tripolyphosphate zinc powder nokunye. Njengamanje, upende ovimbela ukugqwala usetshenziswa kakhulu ekumbozeni okulwa nokugqwala, futhi izindleko zopende ovimbela ukugqwala zingu-6%-8.5%.

Uyini umehluko phakathi kopende olulwa nokugqwala nopende?

Upende wokulwa nokugqwala uhlobo lopende olungavikela izindawo zensimbi ekugqwaleni kwamakhemikhali noma kwe-electrochemical komkhathi, amanzi olwandle, njll. Upende wokulwa nokugqwala ngokomzimba nangokwekhemikhali, njengobomvu bensimbi, i-aluminium powder, upende wokulwa nokugqwala we-graphite, i-red lead, upende wokulwa nokugqwala ophuzi we-zinc nokunye.

Upende luyinhlanganisela yamakhemikhali emboza ngokuqinile ubuso bezinto, ivikele, ihlobise, ibeke uphawu kanye nezinye izinjongo ezikhethekile, futhi yakhe ifilimu eqinile enamathela ngokuqinile ebusweni bezinto futhi inamandla athile kanye nokuqhubeka.

1. Imisebenzi ehlukene:

Upende ovimbela ukugqwala unezimpawu zokulwa nokugqwala kanye nokulwa nokugqwala, ifilimu iqinile, isebenza kahle kakhulu, futhi ubulukhuni buphakeme kunopende ojwayelekile. Upende ojwayelekile awunawo umsebenzi wokulwa nokugqwala, ngoba izinto ezivamile zefilimu yopende ziyi-alkyd resin, ngokusebenzisa i-oxidation kanye nokomisa, ubulukhuni obubi, igebe lebanga lokunamathela.

2. Impilo yesevisi ehlukile:

Upende ovimbela ukugqwala ungasetshenziswa iminyaka emi-5-8 uma uhlanganiswa. Upende ojwayelekile uvame ukusetshenziswa ngaphandle iminyaka engaba mi-3. Ngemva kweminyaka emibili noma emithathu, kulula ukuwa, ukubuna kanye nophuphu.

3. Izinhlobo ezahlukene:

Upende ovimbela ukugqwala: upende ovimbela ukugqwala we-phenolic, upende ovimbela ukugqwala we-alkyd (obomvu bensimbi, ompunga, ulethi obomvu), upende ovimbela ukugqwala ngerabha ene-chlorine, upende ovimbela ukugqwala we-epoxy (upende ovimbela ukugqwala we-zinc phosphate, upende ovimbela ukugqwala we-lead obomvu, upende ovimbela ukugqwala ocebile nge-zinc, upende ovimbela ukugqwala wensimbi obomvu), njll.

Upende: Izinhlobo eziningi zopende, upende olulwa nokugqwala luwuhlobo lopende, ngaphezu kopende kuhlanganisa nopende wokhuni, upende waphansi, upende wangaphandle wodonga, upende wamatshe, upende onemibala eminingi, upende we-aluminium alloy, upende ongashi, upende we-latex nokunye.

Iziqondiso eziyisishiyagalombili zokuthuthukiswa kwesikhathi esizayo kopende olulwa nokugqwala

Okokuqala, ukuthuthukiswa kwe-primer elwa nokugqwala esuselwe emanzini kanye nopende ophezulu wezakhiwo zensimbi.

I-primer yokulwa nokugqwala esekelwe emanzini kumele ixazulule ukukhungatheka kwe-substrate "flash rust" kanye nokumelana kwamanzi okungekuhle, futhi ukwanda kwama-emulsion amasha angenayo i-emulsifier kuthuthukise kakhulu isihloko sayo sokumelana namanzi okungekuhle, futhi ikusasa kufanele ligxile ekuxazululeni izinkinga zomsebenzi wokwakha kanye nomsebenzi wokusetshenziswa. Njenge-topcoat, ihloselwe kakhulu ukuthuthukisa ukuhlobisa kwayo kanye nokuqina kwayo ngaphansi kwesimo sokuqinisekisa umsebenzi wokuvikela.

Okwesibili ukuthuthukisa uchungechunge lokuqukethwe okuphezulu okuqinile kanye nopende wokulwa nokugqwala ongenazo izinyibilikisi.

Ukubhoboza, amapulatifomu asogwini kanye namaphrojekthi amakhulu okulwa nokugqwala emsebenzini wokulwa nokugqwala ohlala isikhathi eside wezidingo zokumboza kuyaphuthuma kakhulu, imakethe yamanje ngokuyisisekelo iyizinkampani zakwamanye amazwe kanye nemikhiqizo engenisiwe esetshenziswayo. Imikhiqizo yaseShayina isezingeni lobuchwepheshe, amandla ezomnotho, uhlelo lokuqinisekisa ikhwalithi kanye nedumela lomkhiqizo kanye neminye igebe lamandla eliphelele namazwe angaphandle, kunzima ukungena emakethe. Ukuze kufezwe lokhu, okokuqala, kufanele kwenziwe imizamo ekuthuthukisweni kobuchwepheshe, ikakhulukazi ukuthuthukiswa kwe-primer ye-pigment engenalo i-lead kanye ne-chromium-free anti-rust, okungukuthi, ngokusekelwe ku-primer ye-zinc phosphate kanye ne-aluminium tripolyphosphate anti-rust.

Okwesithathu ukuthuthukisa i-primer ecebile ngamanzi ene-zinc.

I-primer ecebile nge-zinc engaphili kanye ne-primer ecebile nge-zinc engaphili engaphili engaphili ingenye yama-primer asebenza isikhathi eside, kodwa ayizimbozo ezisekelwe ku-solvent. I-primer ecebile nge-zinc engaphili engaphili engaphili engaphili ene-potassium silicate ephezulu njengezinto eziyisisekelo iyimbozo yokulwa nokugqwala esebenza kahle evivinywe ngokuzijwayeza futhi inamandla okuthuthukiswa.

Okwesine ukuthuthukiswa kwe-heat exchanger evikela ukushisa evikela ukugqwala.

Ama-heat exchanger adinga izembozo ezilwa nokugqwala ezinokumelana nokushisa okuphezulu kanye nokushisa okuphezulu, kanti i-epoxy amino coating esetshenziswayo njengamanje idinga ukucwiliswa ku-120 ° C futhi idinga izembozo eziningi, ezingasetshenziswa kumadivayisi amakhulu.

Okwesihlanu ukwakha ungqimba olungaphola uma izinga lokushisa legumbi lishisa futhi kulula ukulifaka.

Iphuzu elibalulekile ukuthola ibhalansi engcono kakhulu phakathi komsebenzi wokuvimbela ukugqwala, umsebenzi wokudlulisa ukushisa kanye nomsebenzi wokwakha wengubo.

Okwesithupha ukuthuthukiswa kwengubo yokulwa nokugqwala evuthayo.

I-Mica iron oxide (MIO) inokumelana okuhle kakhulu kwe-dielectric, ukumelana nokuguga emoyeni kanye nomsebenzi wokuvimba, futhi isetshenziswa kabanzi njengopende wokuqala kanye nopende ophezulu eNtshonalanga Yurophu.

Okwesikhombisa, ukuthuthukiswa kochungechunge lwenjoloba olune-chlorine lwezinto ezithatha indawo yengubo yokulwa nokugqwala.

Ngenxa yokuthi irabha ene-chlorine iyisici esisodwa, ukwakhiwa kwayo kulula, ukumelana namanzi, ukumelana nowoyela, ukumelana nokuguga emoyeni kuhle kakhulu, kusetshenziswa kabanzi ekwakheni imikhumbi, ekuvimbeleni ukugqwala kwezimboni nakwezinye izinkambu, kunemakethe ebanzi eShayina. Kodwa-ke, ngenxa yokuthi ukukhiqizwa kwerabha ene-chlorine kusebenzisa i-CC1 njengesinyibilikisi, ungqimba lwe-ozone luyabhujiswa.

Okwesishiyagalombili ukuthuthukiswa kwezinto zokuvimbela ukugqwala ezingaphili eziguqulwe ngendlela engokwemvelo.

Eminyakeni yamuva nje, ukusetshenziswa kwe-organic emulsion kushintshe ukhonkolo ukuze kuthuthukiswe amandla ayo, ukumelana okuphakathi, okusetshenziswa kabanzi ekumbozweni phansi kwezimboni. Phakathi kwazo, i-epoxy water emulsion (noma i-epoxy esekelwe ku-solvent) ithuthukisa esheshayo, ebizwa ngokuthi i-polymer cement.

Mayelana NATHI

Inkampani yethuibilokhu inamathela njalo ku-"'sayensi nobuchwepheshe, ikhwalithi kuqala, ukwethembeka nokuthembeka, ukuqaliswa okuqinile kohlelo lokuphathwa kwekhwalithi lwamazwe ngamazwe lwe-ls0900l:.2000. Ukuphathwa kwethu okuqinile ubuchwepheshe bokusungula, isevisi yekhwalithi esezingeni eliphezulu, ithole ukuqashelwa yiningi labasebenzisi.Njengochwepheshe, ifektri yaseShayina ejwayelekile futhi eqinile, singanikeza amasampula kumakhasimende afuna ukuthenga, uma udinga upende ovimbela ukugqwala, sicela usithinte.
